Frank whipped out his pocket knife in a jiffy. Ned touched a lever near the motor, and things went whirring. There was a busy hum that made the place delightful to Frank. He was astonished and pleased to observe how deftly his companion handled the knife, putting it through a dozen operations, from grinding to stropping and polishing. Then he adjusted a little drill to a handle and said:
"I'll put your name on the handle, if you like."
"All right," assented Frank with satisfaction. "It's Frank Jordan."
"There you are," said Ned a minute later, handing the knife back to Frank. "You'll find a blade there that will cut a hair."
"Yes, that's fine work," declared Frank, looking over the knife in a gratified way. "You've got quite a trade, haven't you?"
